CHAPTER I
A. BACKGROUND
Reality which increase demand all the mankind to mobilisator, which mean where the duration and cost must we calculate. Effective and eficiency to entry data getting more we could have by using several science and technology especially by computer.
By using computer, all the problem such as hardest work that we have to finished as soon as possible he could execute just for several minutes and more accurate. Kinds of mass transportation that we can see in Semarang generally have different cost that become competition beetween them. Affect to our daily activities. Transportation development we couldn’t forget that we need them but in sistematically. Sometimes, several society not used it and ignore about transportation in this country especially programming sistematically and government either.
Mathmatics applied can developed and studied by using operational research (OR) where this Or become methods to solve optimatically problem. A lot of operational research models that have been developed which relation with math. One of them is network analysis derivate from linear program.network theory told us about problem solver in project management included planning, scheduling, and project evaluation.
The important factor to succed in increase operation reserch applied is development that information technology (IT). Since began operation research methods need computing process intencivelly. Development in this several years affected to some complicated problems and other side, the complicated problems appears from operation research cases that make new problem affect to research in technology.
Since this cases, the research interested in learn computing programming in information technology with kind of solving from operation research cases. Nowadays, computing science interested in lindo programming then we modify to problem that we faces. By using lindo programming, the solution quickly and less from mistakes then we analysis according to the problem. In this cases, project scheduling will be review to find critize path therefore we can get how long the project must been done.
The duration until finished not often with calculate all the whole times in activities, but we simplify with find the critize path. Critize path is path which direct activities start from beginning until the end of all project. How to use the critize path which mean by using evaluation methods, included critize path methods, linear program methods. In this final works, we will find accurate methods and how to choose trip and mass transportation also competitive cost according to user will and interpelate in visual basic 6.0 programming the result from PERT CPM ( Project Evaluation And Review Technique dan Critical Path Method). Why we use planning program and project controlling with PERT-CPM to execute project problem above is so benefit because a project definitive of one combination all the activities related with others then we queue in special line before all the activities finished. This activities related with others as logical queue which mean several activities could not started before others activities can they finished first, so in this problem we can start to make effectively and efficiency in Semarang mass transportation. An activity is part of the project as a work which need couple times and also resources to finished then generally a project is one act with one respon that can redundant. Remind the project of efficiency mass transportation in Semarang have several variables, so we have weakness and manual calculate. Therefore, the advantage this programming is to make easier than manual. With complicate reality makes scheduling especially in trip mass transportation in semarang project become interpretate in planning. Finally, the important problem in route mass transportation in semarang at least it is not makes new problems that more harder with eliminate non benefit from wrong planning which is dependent to several activities especially effectively of trip or route path in mass transportation in semarang then we cant determine. This is the position of lindo programming and also systematic approach from planning PERT-CPM which mean to make easier complex then increase from couples of problems that exist. Complecity makes simplify methods and give the result to efficiency optimum in project action that relation within. Efficiency have to relate with the available resources.
Even when realization to answers project problem of trip mass transportation in Semarang become our inspiration as a writer that more focus on computing approach, but in execute the primer data obviously need modeling into computing language model as an explanation to society about how to realize the project problem above.
In this final work, the researcher will explore about programming applied in project management, by critize path from project of mass transportation in Semarang and then find the efficiency value where we hope more effectively and efficiency that the goal we expected.
B. PROBLEM
According to problem background above, therefore the reseach problem below:
1. Determine result from critize path analysis in case of trip or route mass transportation start from January 2007 until December 2007 by lindo programming.
2. How the result from critize path analysis with lindo programming then execute with Visual Basic 6.0 and we could know society potencial market especially mass transportation in Semarang.
C. MEAN DEFINITION
1. Shelter
According to An English Indonesian Dictionary by John M Echols and Hassa Shadily published PT Gramedia Jakarta that mean shelter is a noun for protecting. 2. Cover up. Adverb 1. give some space, stay at, cover up, hide from. Shelter interpretate in homonym, homograf, homophone, without lost the real mean and become new word in Indonesian language.
2. Lindo Programming
Lindo programming is one of several computer software base on window system. Lindo programming used to execute kinds of problem related with linear form object.
- Microsoft Visual Basic 6.0
Microsoft Visual Basic 6.0 is one of computer programming included into software which is a lot of user in Indonesia use it and industry to execute the data or networking system program. Base on Microsoft Visual Studiowhere in inside we can found different language.
4. Project schedule
Schedule mean divide times according to finished some activities with special order directly.
5. Critize Path
Path is the way that we have to passed or brakethru in inside (Tim penyusun KBBI,1996:597). Critize is condition where most decide for our goal or our mistake of activities (Tim penyusun KBBI,1996:531). Critize path is path or way which cross road or passed, in other word, critize path is path where we decide to finished the whole project.
D. PROBLEM MEASUREMENT
Schedule project management which we explore in this final task is about optimize or schedule prject efficiency in mass transportation route in Semarang start from January 2007 until December 2007.
E. RESEARCH GOAL
This research goal are below :
1. To know how determine of critize path from mass transportation route in Semarang by using lindo and software such as Microsoft visual basic 6.0.
2. To visualize lindo analysis result and we explore in Microsoft Visual basic computer programming.
F. RESEARCH BENEFIT
Research which we are explore route mass transportation in Semarang expected where the result can give benefit to all mankind.
1. For education we can practize about scheduling technic in reality by watch the condition in field which is so complicated and related one kind to others.
2. For institution especially Dinas Lalu Lintas dan Angkutan Jalan Semarang could give references to compare the duration and available budget in order to more effective and efficiency.
3. For government in district, province, and state government can determine which kind of critize activities for whole project. Therefore, we can know much about which activities we have to work hard than other activities that may delayed the schedule.
4. Society in generally, such as user of mass transportation in Semarang.
G. FINAL TASK SYSTEMATIC
This final task according to the systematically divide in 3 parts, first part, substance part, and last part.
